James Hansen has provided proof over the last few decades that climate models are worthless as climate prediction tools - will NASA & the IPCC admit failure?

Using the December-end temperature anomalies (chart on left), it is readily apparent that NASA's James Hansen is entirely incapable of producing accurate global temperature predictions over the long-term. His predictions have been so bad that even the mainstream press is finally coming around to the realization that the alarmist global warming scenarios are truly without merit.

The second chart (on the right) exhibits the non-predicted deceleration of global temperatures over the last 15 years using the IPCC's gold-standard HadCRUT dataset.

Whether it is long or short-term, Hansen/NASA models are no better than a Ouija board as a tool to predict global temperatures. This massive failure by Hansen et al can also be seen in his model's prediction of ocean heat content and sea level rise.
